upgrading to 25.07, if_pppoe and new bug or what?
-
@stephenw10 yep, in 24.11
-
Ok and you're seeing that continuously? Not just after a reboot or re-connection?
-
@stephenw10 Rebooted twice, log entries continue to appear every two to three seconds.
-
Can you show the output from:
pppcfg pppoe0 -
@stephenw10 dev: igb1 state: session
sid: 0x47fb PADI retries: 1 PADR retries: 0 time: 10:12:30
sppp: phase network authproto auto authname "MYUSERNAMEHERE" peerproto auto
dns: dns1 dns2 -
Hmm, seeing that error implies pfSense is seeing pppoe packets from different session on the interface. Normally that would only ever happen immediately after boot or reconnecting when the server side still has an old session active. But it should time out shortly after that. If you're seeing them continue something else is happening.
We might need a packet capture to see what's happening there. -
@stephenw10 Yes, I also assumed that it might not be a closed old session on the provider side. I will monitor for some time. Thank you.
-
@stephenw10 I've been watching for two days - nothing has changed, still a lot of spam in system.log "pppoe: alien host unique tag, no session found". Disabled "Use if_pppoe kernel module for PPPoE client" and rebooted - now the log is clean.
-
That error is from the PPPoE module so it won't show if you're not using it even if they are still arriving.
Not much we can do here without more data. I suggest trying to capture these rogue packets on the WAN in a pcap.

I can confirm this is fault with the ISP , In my case ISP keep the ipv6 session alive even if i disconnect and i wont get any v6 connectivity on subsequent connection , i have to contact isp to give me to fix it. they will assign me a new block but wont invalidate old session. i send them captures both as photo and pcap, i still failed make them understand that their BRAS have bug. when upgraded to if_pppoe this started filling the system log. Is there any way to silence this message ? does github has if_pppoe source for public to take a look ?
attaching capture for RA messages in two different sessions

Ah, that's fun*. Not currently there isn't, either source or a way to suppress it as far as I know. We are adding more refined logging output now.
